APPARATUS FOR COOLING LIQUIDS.

SPECIFICATION forming part of Letters Patent No. 599,202, dated February 15, 1898.

Application filed October 28, 1896. Serial No. 610,324. (No model.) I

T on whom it may concern.-

Be it known that I, WILLIAM L. SPOON, J r.

of Burlington, in the county of Alamance and- State of North Oarolina,-have invented a new and Improved Apparatus for Cooling Liquids, of which the following is a full, clear, and exact description.

The invention relates to'apparatus for cooling hot water or other liquid used in ice-machines and the like; and its object is to provide a new and improved apparatus'for'cooling water and other liquids in a very simple.

, and effective manner and permitting of using the liquid over and over again with a minimum percentage of loss by evaporation.

The invention consists of certain parts and details and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional side elevation of the apparatus. Fig.2 is an enlarged side elevation of the combination water and air nozzle, and Fig. 3 is a sectional plan View of the improvement on the line 3 3 of Fig. 1.

The improved apparatus is provided with a nozzle A, held on one end of a liquid-supply pipe B, through which flows the hot liquid to be cooled. The nozzleAis surrounded by a nozzle 0, connected with a pipe 0, surrounding a part of the supply-pipe B and opening into the outer air, so that the liquid ejected through the openings in the nozzleA creates a suction in the pipe 0, so that the inrushing air acts on the waterissuing through the nozzles A and O to atomize the liquid, so that the latter is atomized and sprayed by the two nozzles. The nozzle 0 isv arranged within a perforated casing D, supporting the pipe 0, and connected at its upper end with an outlet-pipe E, containing a suction-fan F, of any approved construction.

The bottom of the casing D opens upon an inclined perforated plate G, discharging at its lower end on a second plate G, inclined in an opposite direction and discharging on a third plate G likewise inclined, but in an opposite direction to the plate G. Plates G G G and G are arranged one below the other and alternately inclined in opposite directions to form a series of such perforated plates, one.

connects with a trap I, through which passes the cooled liquid back to the apparatus or machine for further use.

Now it will be seen that when the suctionfan F is in motion a current of air passes through the casing D and the leg H, so that the liquid sprayed by the nozzles A and O is subjected to a current ofcool air to cool the liquid by accelerated evaporation. The sprayed liquid from the nozzles falls upon the first inclined plate Grand flows down the same with the air passing up through the perforations in the plate,-the liquid finally passing in a zigzag manner over the several plates in the leg H. to finally arrive in a cool state at the trap I, from which the liquid is returned to the machine for reuse. It is expressly understood that the liquid is atomized and sprayed in a very finely-divided state and then subjected to a current of air of ordinary or low temperature, so that anaccelerated evaporation and a consequent cooling of the liquid takes place.

It is further understood that when the sucseveral plates G G G G G G G are inclosed tion-fan F is in operation the density of the I air is at once reduced within the apparatus, and to restore this reduced density to that of the outer airv an inrushing current begins at once to set in through the perforations in the through the above-named perforations eX- pands, being in a region of less density, and hence the air is rendered cool by expansion, which expansion takes place either in contact with the sprayed water within the casing'D' or as it passes in a zigzag flow against or over the plates G G G G (to. Thus in spraying a hot liquid in an expanding current of rarefied air I accelerate evaporation.

By making the perforations in the casing D and leg H small and increasing the size of the pipe E and the efficiency of the suctionfan F the difference in density of the air within the apparatus and that of the outside air may be made so considerable that, though the water enters at a temperature of 200 Fahren heit and the normal heat of the outside air may be even 100 Fahrenheit or 110 Fahrenheit, the water discharged from the machine may be reduced to a temperature as low as Fahrenheit.

Having thus fully described my invention, I claim as new and desire to secure by Letters 7 Patent- 1. An apparatus for cooling liquids comprising a perforated casing, means connected with the upper end of the casing for forcing zi za le containin erforated lates and t: C: b b

supporting the said casing, substantially as shown and described.

2. An apparatus for cooling liquids, comprising a perforated casing, means for forcing a current ,of air through the said casing, a nozzle connected with a liquid-supply for spraying the liquid within the said casing, a zigzag leg connected with the said casing and having perforated tops, and perforated plates within the members of the said leg, substantially as shown and described.

3. An apparatus for cooling liquids, comprising a perforated casing, means for forcing a current of air through the said casing, a nozzle connected with a liquid-supply for spraying the liquid within the said casing, a zigzag leg connected with the said casing and having perforated tops, and perforated plates within the members of the said leg, and a trap connected with the lower end of the said leg, substantially as shown and described.

4. In an apparatus for cooling liquids, the combination with a perforated casing, means for forcing air through the same, and a nozzle arranged in the casing for spraying the liquid in the said casing of a zigzag leg communicating with the casin g and through which the water from the casing passes, said leg having the tops of its members perforated, substantially as described.

5. In an apparatus for cooling liquids, the combination with a casing, means for forcing air through the same, and a nozzle for spraying the liquid in the casing, of a zigzag leg communicating withthe casing, the tops and half of the sides of the members of the legs be ing perforated, and inclined perforated plates in the members of the legs, substantially as described.
